The answer is the second choice, or B; 240 ft^2.
You have to find the area of all four triangles and just add those all together.
Two of the triangles have an area of
5*16=80
Multiply that by two
80*2=160
The other two smaller triangles have an area of
8*5=40
Multiply that by 2 also
40*2=80
Add 160+80 and the answer is 240.

Answer:
1440°
Step-by-step explanation:
n = number of sides
n-2 x 180
10 - 2 = 8
8 x 180 = 1440°
8x-12 = 5+15
8x-12 = 20
8x = 32 +12
x = 4 ÷8
